SELECTING INSTRUM ENT.

SPECIFICATION forming part of Letters Patent No. 626,806, dated June 13, 1899.

To all whom, it may concern.-

Be it known that I, ANTON DU PPLER, of Jersey City, New Jersey, have invented a new and useful Improvement in Selecting Instruments, of which the following is a full description.

The accompanying drawings illustrate the invention, of which Figure 1 is an upright front view showing the framework in section and the operating mechanism in full lines. Fig. 2 is a side view of the mechanism of the device, looking in the direction of the arrow in Fig. 1. Fig. 3 is an illustrative diagram showing one of the adaptations of the selectorto an indicator for baseball or other sport.

The general features of the improvement consist in part of the use of two magnets having a common current received from a suitable transmitter, one of which responds promptly and turns a contact-arm and the other responds only when the impulses stop for a moment and the current is allowed time to operate it.

The magnets are represented in the drawings by the letters A and B. The latter, B, is the prompt magnet, which responds at once and performs the work of turning the contact-arm in response to the impulses, and A is the magnet which acts when the impulses cease and makes contact between the arm and its appropriate contact-point. Both of these magnets are suitably secured to the frame C. J ournaled in the frame is a shaft D, arranged to slide laterally and provided with the ratchet-pinion and pawl cl 61 the latter placed upon theend of the armature-lever b actu ated by the magnet B. The current from a battery enters this magnet through the conductor e, passing out through 6, through the magnet A, back to the battery, and within this circuit may be placed a suitable impulse-trans mitting machine. As these impulses pass through the coils of magnet B they actuate p the escape-wheel (1 step by step, turning with it the shaft D, which carries a contact-arm (l and affixed to the frame is an insulated disk F, provided with the contacts f f &c., and each impulse through the magnet B brings this arm successively in front of one of these contacts, and as the impulses are given rather Application filed August 18, 1897. Renewed December 2, 1898. Serial No. 698,067. (No model.)

rapidly the arm passes in front of the contacts without touching them until the impulses stop while the current is still acting, and this brings into operation the magnet A. The armature of this magnet is arranged upon a sliding shaft a provided with a strong resistance-spring a while the armature itself stands farther out from the core of the magnet than that of the magnet B. As a consequence, while the arm (Z is turned until it presents itself in front of the selected contact, then the magnet A draws its armature, and as the shaft D is also a sliding shaft and is connected with the shaft (1 by the arm a it is also slid laterally, carrying with it the arm (Z and bringing it into contact with the selected point on the disk F. The escapement-pawl on the end of the lever b is wide enough at its end to still retain its place in the teeth of the ratchet-pinion when the shaft D is slid laterally and remains in its place,

holding the shaft and preventing it from turn-'- ing in one direction, while it is prevented from turning in the opposite direction by another pinion d mounted on shaft D, and a checking-arm d suitably secured to the frame.

The arrangement is more fully shown in Fig. 3, where the device is shown in one of its adaptationsfor example, to indicate positions on a base-ball fieldwherein it is shown that the contact-stops on the disk F are each connected with one terminal of a local circuit, all having a common return to the arm 61 and in each of the circuits is placed a magnet- I. In the diagram Fig. 3 these circuits may be readily traced. The arm 61 is shown in the diagram to be in contact with one of the pins on the disk F. Starting from that pin the circuit runs through the magnet I to one side of the local battery and from the other side to the shaft D, on which the arm d is secured, which when in contact with this pin closes the circuit, and so from the next in above,and also with the second one above, as illustrated. Each of these circuits has a magnet and each actuates a disk G step by step, which disk is mounted upon a shaft provided with a ratchet-pinion g actuated by a ratchet-pawl g ,connected with the armature of the magnet I. The indications may be made in a variety of ways, as the disks may contain any kind or character of color, symbol, or figure, only one of which need be described. Suppose a base-ball bulletin-board be provided with aseries of openings at which are to be shown the position of batter, baserunner, pitcher, or fielder, and in front of each of these openings is located one of these disks. Now in Fig. 3, starting from zero, the disk is in front of the opening shown in dotted lines at the top and presents a blank. Now let us suppose that this particular disk is intended to illustrate first base. runner arrives at this point, a single impulse brings down the armature of magnet I and turns the disk to the point occupied by the numeral-1, and this shows the base to be occupied and remains in this position until the base-runner leaves first base, when a change is made by any impulse or impulses sent out from the transmitter. Any impulse sent therefrom will take the arm d from its contact-pin, and as this opens the circuitthrough the magnet I its armature is thrown up by its spring and the pawl throws the disk to the position shown by numeral 2. If, therefore,the

colors orblanks and figures, a blank would immediately be shown at the opening in the bulletin just occupied by a signal, and as each of the openings in the bulletin-board is provided with one of these disks and as each disk has its representative pin on F any kind of signal may be shown on the bulletin. Any suitable transmitting instrument may be used for the purpose. A good one is illustrated in Fig. 3, in which II is a stationary disk, through which protrudes the shaft 71 having a con ducting- .ring 713, provided with insulating stops or pins 7L and conducting-spaces 7r. Attached to the shaft is an arm h, and the shaft is revolved by suitable mechanism, such as a spring or a cord and weight. (Not shown in the drawings.) One terminal of a main-line or other circuit is attached to the shaft and the other to a conducting-spring 7L7, suitably secured to the disk. The current traverses the coils of the relay-magnet K, whose armature closes and opens the circuit through the magnets A and B of the selector. Arranged around the disk II of the transmitter are a series of stop-pins normally placed so that the arm 71, may turn, but which may be pushed down, so as to stop the arm at any point.

Let us suppose the disk G, representing first base, is actuated by the current from the local battery represented by the contact-pin N o. 5 on the disk F of the selector, and this position is desired to be shown occupied.

arm 716 of the transmitter is stopped at zero by one of thepins. Counting five from this point, that pin is pressed down and the zero-pin pulled out, the shaft h turns, and the spring 7&7 I passes upon the conducting-spaces and insulating-points successively, making the live im- When a The l required signal before the opening in the bulletin-board which is thrown off a ain as ex- I 3 1'3 plained above.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
